Subject: Tamara Kolda Receives Householder Fellowship

I am pleased to announce that Tamara G. Kolda is the recipient of the
1997 Householder Fellowship in Scientific Computing at the Oak Ridge
National Laboratory (ORNL). Tamara received her Ph.D. in Applied
Mathematics from the University of Maryland at College Park under the
supervision of Dianne O'Leary. The title of her dissertation is
"Limited-Memory Matrix Methods with Applications". Tamara's research
interests include numerical linear algebra and optimization. Tamara
joined the Computational Mathematics and Statistics Section at ORNL
in July, 1997.

The Householder Fellowship honors the late Alston S. Householder,
founding Director of the Mathematics Division (now Computer Science
and Mathematics Division) at ORNL, and recognizes his seminal
research contributions to the fields of numerical analysis and
scientific computing. The Fellowship is supported by the Applied
Mathematical Sciences Program at the U.S. Department of Energy.

Subject: New Version of LOQO

Announcing LOQO 3.07 and a MATLAB interface for LOQO.

Dear Friends/Colleagues:

I'm pleased to announce the availability of a new version of LOQO,
version 3.07, which has dramatically enhanced capabilities. This new
version solves convex optimization problems to optimality and
nonconvex ones to local optimality. While a subroutine library
still exists, the simplest way to feed a nonlinear optimization problem
to LOQO is via the math programming language AMPL. This is the default
mode of operation. This new AMPL interface makes nonlinear optimization
with LOQO just as easy as linear optimization. As usual, LOQO is free
for academic use and can be downloaded directly from my home page:

Preliminary results showing performance superior to both MINOS and LANCELOT
on most large problems will be presented in Lausanne.

I'm also pleased to announce that there is now a LOQO/MATLAB5
interface which allows matlab users to call LOQO from within
matlab to solve large-scale sparse quadratic programming problems.
The syntax for calling LOQO from within matlab is the same as
for matlab's qp(), found in matlab's optimization toolbox,
except that the constraint matrix A and the Hessian H are assumed
to be stored as sparse matrices:

[x,lambda,how] = loqo(H,c,A,b,l,u,x0,neqcstr,display);

I think you'll find loqo() to be vastly superior to qp() in terms of
both speed and robustness. Further details/instructions can be
obtained by visiting my home page.

Subject: New Book on Computational Transport Phenomena

A new book in computational transport phenomena is available:

Computational Transport Phenomena
Cambridge University Press
ISBN: 0-521-55653-8 (PB)
0-521-55378-4 (HB)

"Transport Phenomena" is the generic term for the basic equations
of momentum, heat and mass transfer, which in general are PDEs,
e.g., the Euler and Navier-Stokes equations of fluid mechanics
(momentum transfer). This book is an introduction to numerical
methods that can be used to solve problems in transport phenomena,
presented through detailed examples. Each chapter is a self-contained
discussion of an application including:

(1) The problem ODE/PDEs, motivated by physical considerations.

(2) Introduction to the numerical methods used to solve the
equations of (1).

(3) A computer code to solve the problem equations based on
the numerical methods of (2).

(4) The properties of the numerical solution with emphasis
on physical interpretation and analysis of errors.

(5) A derived analytical solution, when available, or the
features of the problem equations that preclude an
analytical solution.

The mathematics ranges from integrals and initial/boundary value ODEs
to multidimensional PDEs. The computer codes (Fortran source) are
available by downloading from:

Alternately, the software is available on request as a DOS-formatted
diskette sent by US mail or international air mail. Additional
information about the book is available from a link between the
preceding URL and the web site of Cambridge University Press.

Questions and comments concerning the book are welcome.

Subject: Studentship at Cambridge University

Cambridge University, in partnership with Greycon Ltd, has secured a
PhD Studentship under the EPSRC industrial CASE scheme for PhD
research on ``Exact optimisation approach to real life applications''.
The goal of the proposed PhD research is to demonstrate the
viability of an exact optimisation approach in tackling more realistic
integer programming problems. Building on the most advanced
optimisation techniques, and using the decomposition approach as the
integrating mechanism, the PhD candidate will develop an optimisation
code and solve practical applications that cannot be confined to
``pure'' models. The work is to be done in close collaboration with
Greycon Ltd, a software company established in London who produce
advanced optimisation software for scheduling and cutting stock
problems. Greycon, who has long experience of bridging the gap between
academic research and industrial practice, will host the PhD
candidate for a period of three months.

A suitable candidate for this PhD research project is likely to have a
first degree in mathematics, computer science, operations research, or
engineering. The candidate must be experienced in linear programming and be
familiar with integer programming, and must demonstrate good modelling
skills and have sufficient background in computer programming
(knowledge of C and ability to undertake code development). The
candidate should also show interest in the planning of manufacturing

The studentship is available from 1 September 1997, for 3 years, with a
stipend of 8 000 UK pounds per annum (+ tuition). Additional income
can be earned through teaching assistantship and/or discretionary payments
by the industrial partner. Candidates must have a minimum of an upper
second class honours (or equivalent) and must satisfy the other EPSRC
criteria for eligibility such as having a "relevant connection with
the United Kingdom" (see web page
"" for details).
